Title: Improved patterning system for knitting machines
Inventor: HALKYARD HAROLD LEES
IPC: D04B15/68
Filed: 1969-11-04
Abstract: 1,270,880. Knitting - machines. S T I B B E MACHINERY Ltd. 12 Oct., 1970 [4 Nov., 1969], No. 53922/69. Heading D1C. Needle jacks 13 of a circular or flat machine are deflected to move a butt 13b from a cam track by a pulsed moving coil selector 21 acting on the jack presser 14. The jack is sprung and its lower end 13a clamped so that the butt 13b is normally in the track 23. The upper end 14b of the presser is normally retained by magnet 35 when the lower ends are forced inwards prior to each reselection by cam 38. Thus the butt 14b2 rides up rise cam 33 taking butt 14b1 above the radially deflecting portion. The jack is therefor unselected, rides up cam 28, and possibly 29, and the corresponding needle is raised to the influence of pivoted cam 27. When the selector is actuated a ram strikes the presser which pivots at 14a so that the lower end is held by magnet 36, and butt 14b2 removed from the cam track. Butt 14b1 is therefor pushed in by cam 33, thereby flexing the upper end of the jack and withdrawing butt 13b from track 23. The jack and needle are not raised. In modifications a sprung or unspurung jack has an operating butt at its lower end. The selector is either pulled so that the ram strikes an aligned jack, or if the ram has a cam face, when the jack is riding up the face. A manually adjustable cam presses all the jack so that their butts are forced out of the track.

Bottle-transfer mechanism comprises a substantially horizontal conveyer (5), Fig. 2 (not shown), adapted to forwardly advance longitudinal rows of bottles in mouth-to-bottom relation; holding arms 17 pivotally mounted on a shaft 23 transverse to the direction of movement of the conveyer 5, and having a downwardly projecting hook 31 on the forward side of the pivot and an abutment 32 on the rearward side; drive means (Figs. 5 and 6) adapted to swing said holding arms between a first position (Fig. 8) in which the hooks are lowered to hold a lateral row of bottles against forward movement, and a second position (Fig. 7) in which the hooks are raised to permit the lateral row of bottles to pass beneath and the abutments are lowered to hold the next following lateral row of bottles against forward movement; and a series of transfer arms 73 positioned beneath the holding arms, and adapted to transfer a lateral row of bottles from beneath the holding arms while the hooks 31 are raised. The driving means comprises an air cylinder (28) (Fig. 2, not shown) which acts on a crank of a shaft 26 to oscillate a V-shaped arm 53 (Figs. 5 and 6) carrying stops 57, 58. These act on a surface 54 of an arm 51 so as to drive the latter between the two positions shown respectively in Figs. 5 and 6. The arm 51 is connected by a spring 55 to an arm 47 carrying a roller 46 which operates on a cam surface 45 of an arm 41 rigid with the shaft 23. The air cylinder 28 is controlled by a microswitch (not shown) actuated by the pockets (90) of a bottle washer which is fed by the conveyer (5). The transfer arms 73 are given their transferring movement by a member 70 rigid with the shaft 26. In addition to rotating the arms 17 between their two bottle holding positions, the shaft 23 is connected by an arm 81 and link 80 to an arm 79 of bell crank 77, 79, mounted freely on a pivot 26A carried by an arm 78 rigid with the drive shaft 26. The arm 77 of the bell crank is connected by a linkage 75, 74 with the transfer arms 73. Thus when the arm 17 is tilted from the position of Fig. 7 to that of Fig. 8, the linkage 81, 80, 79, 77, 75, 74, acts to tilt the transfer arms 73 out of a bottle engaging position during their return travel. The conveyer (5) comprises walking beams (5) carried by cross members (7) resting on actuating cams (8) of drive shafts (9). The conveyer (5) is fed by an endless conveyer belt 2.

Filed: 1971-11-26
Abstract: 1361039 Pressure casting machines IDRA-PRESSEN GmbH 26 Nov 1971 [2 Dec 1970] 54921/71 Heading B3F In a method of pressure diecasting in which pressure is applied to a press piston 2 in three phases, a multiplied pressure is applied to the metal in the mould during the third phase by a multiplier piston 5 which remains at rest during the first and second phases because of a restraining pressure in a chamber 25, said restraining pressure being reduced to permit the movement of the piston 5 after a time delay initiated by the position of the press piston. A pressure reservoir 6 is connectible to the piston 5 via a valve having a closure member 8. With a reversing valve 9 in the position shown, the member 8 is maintained in its closed position since the pressures in spaces 12 and 16 are equal, and a low pressure is applied to the piston 2 by means not disclosed. At the end of this first phase the valve 9 is reversed, the actuation of this valve being dependent on the position of the press piston 2, to cause a higher pressure to be applied to the piston 2. The reversal of the valve 9 also causes the closure member 8 to move to its open position thus enabling the pressure in the reservoir 6 to act on the piston 5. Immediate movement of the multiplier piston 5 is prevented by a counter pressure in the chamber 25 which is maintained until operation of a time delay valve 24 whose actuation is initiated by the reversal of the valve 9.

Abstract: 1455458 Fuel injection pumps ROBERT BOSCH GmbH 28 Nov 1973 [29 Nov 1972] 55064/73 Heading F1A In a fuel injection pump comprising a piston 2 reciprocable and rotatable in a cylinder 4 to pump fuel from a working chamber 12 through a distributing passage 17, 22 successively into delivery passages 33, the delivery of fuel to a respective delivery passage 33 is terminated when a radial port 24 in the piston 2 passes out of an adjustable control sleeve 26 to allow fuel to spill from the working chamber via the distributing passage 17, 22, a respective U-shaped passage 32 in communication with the delivery passage and a piston passage 23, 20, 19 containing a check valve 30. The arrangement of passages and the valve 30 operate to maintain a residual pressure in the delivery passages 33. By arranging for the distributing passage 17, 22 to be closed to communication with each U- shaped passage 32 before the piston passage 23, 20, 19 is closed to communication therewith, pressure waves occurring in the delivery passages can be dissipated through the check valve 30. Preferably the distributing passage is closed before the commencement of the suction stroke to prevent a partial vacuum being produced in the connected delivery passage, but it may be desirable to delay such opening until the suction stroke has started. Movement of the piston 2 is produced by a cam 6 which may be shaped to cause the piston to dwell at top dead centre.

Title: Hydraulic operator and circuit therefor
IPC: E05F15/02
Filed: 1971-12-02
Abstract: 1337167 Hydraulic power door operator STANLEY WORKS 2 Dec 1971 [2 Dec 1970] 56043/71 Heading E2M A hydraulic power operator is mounted in use above a door and a power cylinder 12, under the action of hydraulic pressure from motor 20 and accumulator 52, acts on a vertical spindle 36, about which the door pivots, to open it; the door closes under the' action of a double acting spring biassing means 14 which also acts on the spindle. A valve means 16 normally connects cylinder inlet line 72 to reservoir 54, via line 78, but any suitable detecting means can be employed to actuate solenoid 68 and cause it to connect line 72 to pressure line 71. When this occurs piston 74 is pushed to the right driving the spindle 36, via 138, 140, anticlockwise to open the door and store energy in spring means 14. When the solenoid is deenergized line 71 once more connects with reservoir 54 and the spring means 14 closes the door; valves 73, 80 restrict the passage of fluid to and from the pressure side of the piston and control the opening and closing speed of the doors. The cylinder 12, being below the level of the reservoir, is always full of fluid and the opening movement of the piston forces fluid out of chamber 158 via 162, 164, 166 to the reservoir. When the line 72 is under pressure plunger 222 is depressed and holds ball 224 free of seat 226 to permit free fluid passage; but if the door is opened manually the ball 222 can block 226 and the ejected fluid must pass via restriction 230, limiting the manual opening speed.  Fig. 4 shows the operation of the power cylinder more clearly. Line 72 connects to chamber 148, and when the door is closed section 194 takes up the position shown dotted. Fluid under pressure passes through conduit 150 through one-way valve 152 to act on the piston 74 in chamber 156. When the door is almost open, section 168 enters chamber 160 and forces the fluid being ejected from chamber 158 to pass through restriction 176 to reach the exit line 162, this causes the door to decelerate. A similar deceleration is produced when the door is almost closed, since as 194 re-enters chamber 148 fluid can only pass through restriction 198.  If the door is accidentally opened in the reverse direction the piston will move initially to the left from the dotted position and hydraulic fluid will move past restriction 198. As the door moves further in this direction the drive link 138 reaches an over centre position with respect to spindle 36 and the piston will: move to the right, restriction 230 will limit the flow of fluid as described earlier. Section 194 remains in 148 and when the door closes restriction 198 will affect the flow, then as the over centre position is re-passed movement to the right will be affected by restriction 230. The reverse opening and closing movement of the door is therefore resisted by the passage of fluid through the restrictions 198, 230.
